The Toyota Auris HSD Has Been Revealed — Expect To See It In South Africa

The Toyota Auris HSD has made its debut at the Geneva Motor Show where it will be a full hybrid model. The plan is to make the Hybrid Synergy Drive system an entire range by the early 2020’s.

The Auris HSD will boast CO2 emissions of 89g/km at the lowest. There will be a 1.8-litre VVT-i petrol engine as well as a electric motor. The fuel consumption will be 3.16-litres per 100km.

Power on the Auris HSD will be set at 59kW from the 1.8-litre engine and this will be followed by 142Nm of torque. There will be a 60kW output with 270Nm from the electric motor. The two motors will be able to work together, and they will be limited to 100kW of max power when working together.

Toyota’s Auris HSD will arrive in South Africa as well.

Press Release



Production model unveiled at Geneva motor show


  • Production-ready Auris HSD makes debut at Geneva motor show
  • Built in Britain at the Burnaston factory
  • Offers the latest-generation Toyota Hybrid Synergy Drive to deliver class-leading CO2 emissions and combined cycle fuel economy
  • Two versions to be offered in Europe – delivering 89g/km emissions and 3.16 litres/100km combined cycle fuel economy and 93g/km emissions and 3.3 litres/100 km combined cycle fuel economy
  • Unique proposition in the European C-segment

Exclusively designed for the European market, the Auris HSD (Hybrid Synergy Drive) introduces full hybrid technology to a core model at the heart of Toyota’s model line-up. It marks the first step in the deployment of HSD technology across the company’s entire European model range by the early 2020s.

Built in Britain at Toyota Motor Manufacturing UK’s Burnaston factory, it targets an important shift in customer perceptions of full hybrid drive technology.

Going beyond the benefits of exceptional fuel efficiency and low CO2 emissions that are inherent in Hybrid Synergy Drive, the new Auris HSD will deliver everyday usability, driving comfort and remarkable quietness for a smooth and sophisticated driving experience that is unlike anything else in the C-segment.

Auris HSD will be available in two levels: 89g/km and 92g/km, both offer the lowest CO2 emissions and strongest fuel economy in their class. HSD will thus play a significant role in further reducing Toyota’s European-bound whole-fleet average CO2 emissions. These have already fallen by 14g/km between 2008 and 2009 to 132g/km, thanks to the introduction of Toyota Optimal Drive technology. Optimal Drive technology is already on offer in South African vehicles such as the Corolla 1.3.

Exterior design

The Auris HSD adopts the new exterior styling introduced across the Auris 2010 model range, including a completely redesigned front-end. These design changes are set to be introduced on South African Auris-models in March 2010. The Auris HSD also displays a number of model-specific features which help improve the car’s aerodynamic efficiency and reference the presence of Toyota’s Hybrid Synergy Drive powertrain.

The opening in the upper front grille has been optimised to promote a smooth flow of air over the upper half of the body, and the lower grille has been made larger to reduce airflow resistance and improve engine cooling efficiency. The exterior design is further accentuated by the Hybrid-branding and the blue highlights on the Toyota-logo, a unique feature of all Toyota hybrids.

With a revised foglamp configuration, the flat, vertical surface of the corners of the front bumper corrects the airflow as it passes over the front wheels, helping minimise turbulence in the wheelarches.

Further improvement in aerodynamic efficiency is achieved by a ride height reduced by 5mm; purpose-designed alloy wheels with integrated aerodynamic caps as is seen on the new generation Toyota Prius; low rolling resistance tyres; and a large, roof-mounted rear spoiler. Working together to smooth and control the flow of air over the car, these HSD-specific design modifications reduce the coefficient of drag from Cd0.290 to 0.283, contributing to reductions in fuel consumption and CO2 emissions.

Interior design

The interior features a number of modifications, including a revised instrument binnacle in which the tachometer has been replaced by an Eco Drive Assist Monitor. The centre-dial information panel includes additional HSD-specific information such as Energy Flow and Eco Drive Result monitors.

A hybrid blue smart start button has been added to the side of the instrument cluster and the centre console incorporates switches for the Parking Control and EV, ECO and Power drive modes, and a shift-by-wire gear lever.

The illumination is changed to display greenish-white numbers on a hybrid blue background on the meter panel, audio and heating controls, and the Smart Start, Drive Mode and Parking Control switches.

A choice of upholsteries specific to the model will also be available: a blue-flecked fabric or Alcantara panels with leather surrounds.

Hybrid Synergy Drive

Auris HSD is a full hybrid capable of operating in petrol and electric modes alone, or a combination of both. Its Hybrid Synergy Drive system delivers the energy-saving qualities of a series hybrid (offering power separately in sequence), combined with the performance benefits of a parallel hybrid (where the power of petrol and electric drive is combined).

The technology delivers impressive, seamless acceleration and remarkably quiet running, with class-leading fuel consumption and CO2 emissions from 3.16 litres/100km and 89g/km.

Toyota’s latest generation Hybrid Synergy Drive uses a 1.8-litre VVT-i petrol engine, a powerful electric motor, generator, high performance battery and a power control unit. A power split device with a planetary gear system combines and reallocated power from the engine, electric motor and generator according to the car’s operational requirements.

The key to the successful installation of the system in Auris’s front-engine platform is the fact the electric motor, generator and power split device are housed in a single transmission casing that is the size of a conventional gearbox.  The seamless E-CVT electric continuously variable transmission is controlled by shift-by-wire technology via an electric shift lever.

The lightweight and compact four-cylinder 1 798cc Atkinson Cycle VVT-i engine develops 59kW at 5 200rpm and 142Nm of torque at 4 000rpm. The high performance permanent magnet synchronous 60kW electric motor generates a maximum 207Nm between zero and 13 000rpm.

Powered by the hybrid battery, the electric motor works in tandem with the petrol engine to boost acceleration in normal driving. When the car is operating in EV (electric vehicle) mode, it alone powers the driven wheels.

During deceleration and under braking, the electric motor acts as a high-output generator to effect regenerative braking, recovering kinetic energy that would normally be wasted as heat for storage as electrical energy in the battery.

In combination, the petrol engine and electric motor generated a maximum system power output of 100kW, giving performance to match a conventional 2.0-litre petrol or diesel hatchback. Conversely, Auris HSD lower CO2 emissions and significantly lower NOx emissions than diesel-powered cars of comparable performance.

Furthermore, when operating in its switchable EV mode, it cuts CO2 and NOx emissions to zero, driving for up to 2km at speeds up to 50km/h, depending on the level of battery charge and driving conditions.

Auris HSD eco driving experience

Auris HSD has four driving modes, including three that can be selected ”on-demand” by the driver to maximise the HSD powertrain’s capabilities and provide comprehensive eco driving support for those who want to adopt a more environmentally efficient style of driving.

EV mode allows for ultra-quiet running on electric motor power lone, giving zero fuel consumption and emissions. ECO mode maximises efficiency and fuel economy, and Power mode boosts system performance. In addition, an Eco Drive Monitor helps driver’s maximise the HSD system’s efficiency.

The driver can monitor the flow of energy around the HSD system in each mode, via the multi-information display in the instrument panel, which helps promote an easy, fuel-efficient driving technique. There is also a clear and simple power consumption gauge that shows how much power is being used or generated at any given time.

Taking advantage of the inherent quietness of Hybrid Synergy Drive, Toyota has paid special attention to NVH reduction measures to create a calm and quiet cabin environment at all speeds. Road and engine noise have been rigorously suppressed with extensive use of sound-proofing materials. Full-thickness glazing and a multi-layer acoustic windscreen further reduce noise for quieter performance at cruising speeds.

The Auris HSD is scheduled to go on sale in Europe late in the second quarter of 2010. Although Toyota SA constantly investigate future hybrid models suitable for the SA market no decision has yet been taken on the possible local introduction of the Auris HSD.
